This disclosure relates to the field of manual wrench tools. More particularly, this disclosure relates to manual wrench tools for manipulating a piece of plumbing hardware in a confined or difficult to reach space.
Wrench technology has somewhat advanced over the past couple of decades, but one thing that has not changed significantly is the ability of a wrench to access a piece of plumbing hardware in difficult to reach places. For example, fluid meter yokes are commonly located in subterranean boxes or other difficult to reach locations. In addition to being difficult to access, a piece of plumbing hardware generally require the application of large amounts of force to install or remove as the associated plumbing hardware must be installed tight enough to substantially prevent leaks.
In a typical method of manipulating a piece of plumbing hardware in a difficult to reach location, such as, for example, a water meter valve, two or more persons are required to both manipulate the valve with a wrench and to hold the water meter in place during manipulation. Further, these existing methods frequently require one of the persons manipulating the valve to lie down or kneel so that the wrench may be placed on the desired valve. Thus, manipulating a water meter valve and other pieces of plumbing hardware configured for connection to a fluid meter yoke may be physically strenuous and difficult, if not impossible, for one person to perform.
What is needed, therefore, is a tool for manipulating a valve or other plumbing hardware associated with a fluid meter yoke wherein the fluid meter yoke is located in a difficult to reach location that allows an individual to manipulate the valve or other hardware and reduces the physical strain required to manipulate the valve or other plumbing hardware.
The above and other needs are met by a tool configured for manipulating a piece of plumbing hardware configured for connection to a fluid meter yoke, the tool comprising a wrench member including a wrench head and an attachment portion; an elongate arm member including a proximal end and a distal end wherein the distal end of the arm member is connected to the attachment portion of the wrench member, the arm member configured to optionally extend substantially orthogonal to the wrench member; and a handle member connected to the arm member, the handle member configured to extend at an angle α relative to the lengthwise orientation of the arm member.
The attachment portion of the wrench member may include, for example, a first hinge portion and the arm member includes a second hinge portion adjacent the proximal end of the arm member that is engageable with the first hinge portion of the wrench member to form a hinge providing a hinge connection between the wrench member and the arm member.
The tool further may comprise a first appendage adjacent the distal end of the handle member extending at an angle τ relative to the lengthwise orientation of the handle member; and a second appendage proximate the first appendage, the second appendage extending at an angle σ relative to the lengthwise orientation of the handle member, forming a space between the first appendage and the second appendage for partially receiving an elongate shaft of a separate object wherein the separate object is free to rotate along its length axis while the tool optionally remains unmoved.
Additionally or alternatively, the tool may further comprise a contact portion adjacent the distal end of the handle member extending substantially orthogonal to the lengthwise orientation of the arm member for partially receiving an elongate shaft of a separate object wherein the separate object is free to rotate along its length axis while the tool optionally remains unmoved.
As examples, the wrench head member may comprise a wrench selected from the group consisting of a pipe wrench, pliers, an adjustable wrench and a fixed-width wrench.
In another aspect, a tool is provided for manipulating a piece of plumbing hardware configured for connection to a fluid meter yoke, the tool comprising a wrench member including a wrench head and an attachment portion, the attachment portion including a first hinge portion; an elongate arm member including a proximal end and a distal end, wherein a. second hinge portion is located adjacent the proximal end of the arm member and is engageable with the first hinge portion to form a hinge such that the first arm member is configured to optionally extend. substantially orthogonal to the wrench member; an elongate handle member including a proximal end and a distal end, wherein the distal end of the handle member is removably connected to the proximal end of the first elongate arm member, the handle member configured to extend at an angle a relative to the arm member; a securing structure to secure the connection between the arm member and the handle member; a first appendage adjacent the distal end of the handle member extending at an angle τ relative to the lengthwise orientation of the handle member; and a second appendage proximate the first appendage, the second appendage extending at an angle σ relative to the lengthwise orientation of the handle member, forming a space between the first appendage and the second appendage for partially receiving an elongate shaft of a separate object wherein the separate object is free to rotate along its length axis while the tool optionally remains unmoved.
Optionally, the tool may further comprise a first length portion of the arm member starting from the proximal end of the arm member and a first length portion of the handle member starting at the proximal end of the handle member wherein the first length portion of the arm member is telescopically engageable along the first length portion of the handle member.

Further features, aspects, and advantages of the present disclosure will become better understood by reference to the following detailed description, appended claims, and accompanying figures, wherein elements are not to scale so as to more clearly show the details, wherein like reference numbers indicate like elements throughout the several views, and wherein:
The elongate arm member 14 preferably includes an elongate piece of square tubing. However, it is also understood that the arm member 14 may be formed of circular, ovular, or polygonal cross-sectionally shaped tubing. The arm member 14 includes a second hinge portion 24 located proximate a proximal end 15 of the arm member 14 adjacent the wrench head 12 for hingedly connecting the arm member 14 to the wrench member 12.

The handle member 16 further includes a contact portion 45 shown in
In one embodiment of the present disclosure, the handle member 16 further includes a grip portion 28 (
With reference to
To remove the valve 52A from the water meter yoke assembly 50, the valve wrench 62 may be rotated counter-clockwise along its lengthwise axis relative to the yoke attachment section 58 held in place by the wrench tool 10. To install the valve 52A, the process may be reversed such that the wrench tool 10 secures the yoke attachment section 58 in place while the valve wrench 62 rotates the valve 52A in a clockwise direction relative to the yoke attachment section 58. In an alternative embodiment, the wrench tool 10 may rotate the valve 52A relative to the yoke attachment section 58.
When the valve wrench 62 applies a torque to the valve 52A, the torque is also applied to the yoke attachment section 58 and the wrench tool 10 engaged with the yoke attachment section 58. The torque transfers through the wrench member 12, arm member 14, and to the handle member 16. The handle member 16 is placed directly adjacent the user such that the user holds the wrench in place in some manner (e.g., by holding the handle member 16 against the user's leg) and thereby resists the torque created by the valve wrench 62 turning the valve 52A and thereby allowing the valve 52A to rotate with respect to the yoke attachment section 58 held in place by the wrench tool 10.
The wrench member 12, the arm member 14 and the handle member 16 may be formed of iron, aluminum, copper, titanium and other similar metals as well as alloys made of these and other metals, such alloys including, for example, various grades of steel.
The previously described embodiments of the present disclosure have many advantages, including the advantage of enabling a single user to perform the above-described method of removing a valve 52A from a water meter yoke assembly 50. Other methods of removing the valve 52A from the water meter yoke assembly 50 require a second user to engage the yoke attachment section 58 with a wrench to hold the yoke attachment section 58 in place while a first user manipulates the valve 52A with a valve wrench 62. One embodiment of the present wrench tool 10 allows a user to position the handle member 16 directly adjacent the user's body to prevent rotation of the yoke attachment section 58 while the user installs or removes the valve 52A of the water meter yoke assembly 50. Alternative embodiments of the wrench tool 10 allow the tool to be used in various configurations to allow the tool to engage a valve or other component of a water meter yoke assembly in difficult to reach locations. Further, the wrench tool 10 may be configured for use as a traditional pipe wrench.
